Answer 1

Answer:

(a) x+4

(b)length=16cm and breadth=12cm

(c)192cm^2

Step-by-step explanation:

Let the breadth of the rectangle be x.

•°• length=x+4

According To Question,

2(x+x+4)=56

2x+4=28

2(x+2)=28

x+2=14

x=12

therefore,breadth of the rectangle=12cm

and lenght of the rectangle=x+4

=12+4

=16cm

area of the rectangle=lb

=12cm×16cm

=192cm^2
